In the previous paper, the variation of temperature in concrete caused by the variation of temperature of the air was explained theoretically. In this paper, the measured temperature is compared with the theoretically culculated value and the following conclusions are obtained. (1) The variation of temperature in the concrete caused by the daily periodic variation of temperature of the air can be explained by the temperature distribution equation introduced from the conduction theory with some exceptions. (2) The variation of temperature in the concrete caused by the yearly periodic variation of temperature of the air can be explained by the temperature distribution equation above mentioned without exception. (3) The variation of temperature in the concrete caused by an attack of cold wave of atomospheric temperature when cracking of concrete was found out is able to be explained more by the sudden drop of surface temperature than by periodic variation of temperature for the application of the distribution equation above mentioned.
